A woman who said she was persuaded to invest $450,000 in a bank account seven years ago only found out yesterday that she had been cheated. The woman, surnamed Tang, 40, realised she had lost her money when she went to the Shell Tower branch of the ABN Bank in Times Square yesterday to withdraw her cash and a bank clerk told her receipt was a fake. A report was then made to the police. Ms Tang told officers that in 1996 she struck up a friendship with a woman, surnamed Lai, who worked in a branch of the ABN Bank in Tsim Sha Tsui. After discussing various financial options, the bank clerk persuaded the woman to put her money into a fixed-deposit account that offered her a higher rate of interest than normal accounts. She was told that the account would be automatically extended each year. Ms Tang said she had not touched her account for seven years and had not been particularly concerned when the bank failed to send her any statements about her investment. But she decided yesterday that it was time to make a withdrawal and took her receipt to the bank in Causeway Bay. Wan Chai police, who have been handed the deception case, were last night still trying to trace the former woman bank employee. Earlier, in the same district, a man, believed to be a Pakistani, spilt a milkshake onto the clothes of a middle-aged man who was walking along Percival Street near Jaffe Road at lunch time. As the man, 50, was busily wiping the liquid off his clothes, the Pakistani, believed to be a member of a 'milkshake gang', snatched his briefcase and fled. The victim said his briefcase contained a pocket PC, a diamond ring, $53,000 in cash and his bank and identity cards. Wan Chai detectives said last night they were still searching for the 'milkshake man'.
